Zimbra HTTP Session problem

[zocs]

Whenever we do a browser refresh after login into Zimbra it re-creates an HttpSession. Why is it so? Can't it re-use the same HttpSession?
I also observed similar problem when a user opens another session of the Zimbra UI into another tab of FF.

Is this a bug or know limitation?

Are these sessions handled correctly at the server side?

It reloads the code from the server.

It's neither.

Yes.
